I just screwed up my blog!

I was fiddling around with some new blog settings and I totally wiped out all my carefully constructed blog settings.
Sorry folks! It's going to take a while to get it all back. Some of the items will take some time to figure out too. Please bear with me.
Update Friday 2 Sept: Not everything is fixed, but at least the site is usable again. I guess it was ready for a redesign, but not like that! I really must stop fiddling and get back to work.
